Oxadiazole derivative, light-emitting element material, light-emitting element, light-emitting device, and electronic device
摘要:
An object is to provide a novel material having a bipolar property. Another object is to provide an oxadiazole derivative having a wide band gap. Another object is to reduce power consumption of a light-emitting element, a light-emitting device, and an electronic device. The present invention provides an oxadiazole derivative represented by General Formula (1). In the formula, Ar1 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring, A represents a substituted or unsubstituted phenylene group, R11 to R15 and R21 to R25 are independently any of hydrogen, an alkyl group having 1 to 4 carbon atoms, an aryl group having 6 to 10 carbon atoms in a ring, and a substituted or unsubstituted 9H-carbazol-9-yl group.
